CL05B102KB54PNC

The CL05B102KB54PNC is a multilayer ceramic chip capacitor manufactured by Samsung. This component belongs to the CL05 series, which represents a standard 0402 metric package size (approximately 1.0mm x 0.5mm), making it suitable for compact surface-mount applications where board space is at a premium. Multilayer ceramic capacitors (MLCCs) are among the most widely used passive components in modern electronics. They function by storing electrical charge between multiple ceramic layers with metal electrodes, enabling rapid charge and discharge cycles. The CL05B series is designed for general-purpose applications across consumer, industrial, and telecommunications equipment where reliable performance at modest power levels is required. The "B" designation in this part number indicates the voltage class and dielectric material type used in the capacitor's construction. Samsung's CL05B series capacitors are commonly specified in filtering, decoupling, and coupling applications throughout power supplies, audio circuits, and digital signal processing equipment. These components are particularly valuable in applications requiring stable capacitance across operating temperature ranges and board assembly processes. Engineers typically select this specific part number when designing compact circuits that demand reliable, cost-effective capacitance in applications where space constraints make larger package sizes impractical. The 0402 package size has become an industry standard, ensuring broad compatibility with modern manufacturing equipment and PCB design practices. This standardization also means that the CL05B102KB54PNC can often serve as a direct replacement in existing designs, simplifying inventory management and reducing design qualification time. The part number suffix "PNC" indicates this component meets lead-free and RoHS compliance requirements, making it suitable for applications subject to environmental regulations in the EU, North America, and other regions with similar standards. This is increasingly important for industrial equipment manufacturers who must demonstrate regulatory compliance to end customers. The multilayer ceramic construction of Samsung's CL05B series provides robust performance under typical industrial operating conditions, with the compact size enabling high-density PCB layouts. The component's ceramic construction also provides good frequency response characteristics, making it suitable for both DC filtering and AC signal coupling applications. Industries ranging from automotive electronics to industrial control systems, renewable energy systems, and telecommunications infrastructure commonly incorporate capacitors of this class into their designs. For engineers evaluating alternatives, the 0402 package standardization and Samsung's manufacturing reputation make the CL05B102KB54PNC a dependable choice when upgrading existing designs or developing new equipment requiring proven component reliability and broad supply availability.
